Back to original languageAbout Edouard
With 17 years of experience in the design of microcontroller-based electronic boards, I will assist you in your firmware (embedded software) developments.
To date, I have designed over 25 electronic boards including:
► Connected objects equipped with communications: Ethernet, WIFI, BLE, Zigbee, NFC, Sub-1GHz Radio.
With protocols: HTTP(s), MQTT(s), mDNS, CoAP(s), Cloud: Azure IoT hub...
As security is key, I have specialized in encryption (AES), hashing (SHA-256), digital signature (RSA, ECDSA), security layers (TLS 1.2, TLS 1.3, DTLS), and the implementation of secure bootloaders.
► HMIs with screens: TFT, OLED, custom LCD, capacitive touch on PCB …
► Various PCBs with inputs/outputs such as: USB, SD card, RS485 Modbus, SPI/I2C for sensors and memories, ADC, PWM...
The firmwares are developed in C language with RTOS (FreeRTOS / Azure-RTOS ThreadX) or in cooperative multitasking.
I work with most of the IDEs on the market: ST-CubeIDE, IAR, KEIL, MPLAB X, CLion/VSCode (with Cmake).
As well as the majority of microcontrollers: STM32 (L0, L4, F0, F1, F4, H7), Nordic (NRF52), Microchip (PIC24, PIC32), Renesas, TI MSP430...
Transparency is essential, each mission proceeds as follows:
✓ At the beginning of the mission, a meeting is held to confirm your needs and expectations.
✓ Throughout the development, you will receive a daily report of the work accomplished. You will thus be able to follow the progress of your application.
✓ The source codes belong to you 100%. Every day, I share the code with you on a platform such as Bitbucket or GitHub.
✓ At the end of the development. We will review the project together to confirm that the application exactly meets your needs.
Focused on long-term partnership, my goal is for you to be delighted with the mission and to recommend me.
Do not hesitate to contact me to discuss your project.
